STAVE-CUVTTER.

SPECIFICATION forming part of Letters Patent No. 276,262, dated ,April 24, 1883.

, ApplicationfneaAprii14,1aae (No mdem To all rwhom tt may concern:

Be it known that I, GEO. W. MCKIM, a citizen ofthe United States, residing atM-artins Ferry, in the county of Belmont and State of Ohio, have invented certain n ew and useful` Improvements in stave-Cutters, Vof which the following is aspecication, referencebeing had therein to the accompanying drawings.

My invention consists in certain improvements in the construction of stave-cutters, which will be fully understood by the following description and claims.

In the accompanying drawings, `Figure l is a transverse section of my machine. Fig 2 is Fig. 3 is a detached view.

Upon the frame A is a swinging basket, I, supported on radial. arms having pivots or journal-bearings B. This basket carries the knife-bar D and knife O, and all of these may be rotated upward to a vertical point above A the bearings, and then tilted over to rest on the breast-plate F, out of the way of the worklman, and in a position easily accessible for adjusting the knife-bar, breast-plate, and shear- :plate` without climbing over the frame. `My knife O is made very thin, and is curved to fit the arc in which the knife moves in cutting a stave. This thin and flexible knife is embedded in the knifebar D, which extends nearly the whole width of the knife, leaving only the edge thereof free. By this construction, the Ignite, being thin, cuts moreeasily, and canrbe sharpened with less labor. The knife-bar is made of cast-iron and inflexible. It is also adjustable by means of slots d and set-screws el. The breastplate F supports the shearplate H, which is vertically adjustable by means of slotsfand set-screws G, so as to be kept down close to the knife when swung fon ward` in` its stroke. The stave-bolt is to be placed in Vthe basket I in front of the knife, and as the basket, bolt, and knife are swung forward a stave is cut from the under side ot' the stave-bolt, and falls outof the machine below the knifebar, when the knife returns for the next stroke.

Having thus described my invention, what I claim is-' In a stave-cutter, the swinging basket I, in

combination with the thin knife O1, embedded substantially as and for the purposes set forth.

In testimony whercofI affix my signature in presence of two witnesses.`
